Assignment on kinematic chains.
Type of chain whether it is locked,constrained or unconstrained??
counting number of joints,pair and links.
Tell me any easy way to count these things?
Determine the scalar component of the moment at point 0 about line OB and the reaction at 0 - average normal and shear stresses on plane BB.
What is the enthalpy of this reaction? Assume that no heat is lost to the surroundings or to the coffee cup itself.
Steam at 100 psia, 500oF is throttled to 20 psia. Changes in kinetic energy are negligible for this process. Determine the final temperature and specific volume of the steam.
Determine an expression for the number of cycles to failure, Nf if the initial crack size is a0. State any assumptions you make.
Consider the 2.0micrometer long GaAs device where the E-field is 5kV/cm and Mn*=.067M0. Calculate the transit time of an electron through the device if the mobility is 8000 cm^2V-s.
Consider two-dimensional flow over the double-wedge airfoil shown. Find the lift and drag per meter span acting on the airfoil and sketch the flow pattern. Find the pressure acting on all surfaces.
Determine (a) the turbine work output, in kJ/kg, and (b) the thermal efficiency of the cycle. Also, show the cycle on a T-s diagram with respect to saturation lines.
Depron is a polystyrene foam, popular as a material for the manufacture of fast food trays and packaging. It is much lighter than balsa wood and can be cut with a sharp blade, sawn with a fine.
the cylinder is made from steel where yield stress= 240 MPa and v=0.3. Subsequently sketch the hoop and radial stresses in the wall of the cylinder.
If the peak pressure and peak temperature of the cycle are 4.8 MPa and 2500, determine the net work done per cycle (kJ/kg) and the cycle thermal efficiency .
The system shown anchors a stanchion of cable-suspended roof. If the tension in cable AB is 900 kN, what are the tensions in cables EF and EG?
A refrigerating plant operating between temprature limit of 253k and 307k provides 4.5kJ/s of refrigerating effect. If the refrigerating efficiency of the plant is 0.76. calculate the power required to drive the plant.
